Ⅰ. What is the purpose of oil flash point determination?Answer: Determine the flammability and safety of oil products.Analysis: Flash point refers to the lowest temperature at which the vapor released by a liquid under a specific pressure can instantly ignite when it comes into contact with an igni

I. The difference between kinematic viscosity and dynamic viscosityKinematic viscosity (kinematic viscosity) and dynamic viscosity (dynamic viscosity) are two descriptions of liquid viscosity or flow properties of different physical properties, the difference is as follows:1, the differe

Equipment lubrication is figuratively likened to the "life blood" of the mechanical world, which is not an exaggeration. In various fields such as industrial production, transportation, construction engineering, lubrication is an indispensable link to ensure the normal operation of mechanical equipment. Whether it is a huge factory production line or small mechanical equipment, proper lubrication is needed to reduce friction, cool components, seal critical parts, and prevent corrosion. However, to truly understand the importance of lubrication requires an in-depth understanding of its profound impact on equipment performance and life.

Compressor lubrication refers to reducing friction and wear by adding appropriate lubricants during the operation of the compressor to ensure the smooth operation and long-term reliability of the mechanical components. It is mainly to reduce energy consumption, improve work efficiency, extend equipm

The lower half of the split sleeve bearing has obvious wear and performance failure phenomenon, which leads to the abnormal running state of the cold water pump. The color of the oil sample found in the split sleeve bearing shows an anomaly, appearing green or gray, which is significantly different

A hydraulic system is a mechanical system that uses fluids to transfer energy and is commonly used in a variety of engineering and industrial applications.First, hydraulic system components1. Hydraulic pump: usually driven by motor or engine, used to produce flowing hydraulic fluid. It sucks the liq

The base oils of lubricating oils are the main components in lubricating oil products, which provide functions such as lubrication, cooling, sealing and friction reduction.Characteristics of base oilPhysical characteristicsThe performance of lubricating oil is largely determined by the quali

Poor lubrication and pollution are important reasons for equipment failure:1, 70% of the failure of the equipment is caused by abnormal wear caused by lubrication failure;2, about 40% of the failure and damage in rolling bearings are caused by improper lubrication;3, about 51% of the faults in the g

▲ Condition monitoring area under PF curvePreventive maintenance and predictive maintenance are two different maintenance strategies, which differ in objectives, methods and characteristics. These two strategies can complement each other to improve equipment reliability and reduce costs in mainte
